Synopsis#
Values#
PETSCSF_WINDOW_SYNC_FENCE- simplest model, synchronizing across communicatorPETSCSF_WINDOW_SYNC_LOCK- passive model, less synchronous, requires less setup thanPETSCSF_WINDOW_SYNC_ACTIVE, but may require more handshakesPETSCSF_WINDOW_SYNC_ACTIVE- active model, provides most information to MPI implementation, needs to construct 2-way process groups (more setup thanPETSCSF_WINDOW_SYNC_LOCK)
